In brief: Dietary supplement

The food ; drug administration (fda) does not approve of any dietary supplements, nor is there any need to prove safety ; efficacy prior to marketing w/any number of miraculous claims.
In fact, there is no mandatory 3rd party oversight. The us pharmacopeia provides a voluntary program: dietary supplement verified (http://www.Usp.Org/usp-verification-services/usp-verified-dietary-supplements).
